dev package non-sym link

dev package non-sym link

[Rail Shafigulin]

Somewhat new to Yocto. Trying to build a library. It compiled but I'm
having issues during the package task. The error output is

ERROR: anokiwavelib-1.0+gitAUTOINC+16df62468c-r0 do_package_qa: QA

I do understand the issue. It doesn't create links for libAnokiWave.so
and libAnokiWave.so.1. I do see the following in
/home/someuser/projects/petalinux-build-system/petalinux-build-env/tmp/work/cortexa9hf-neon-xilinx-linux-gnueabi/anokiwavelib/1.0+gitAUTOINC+16df62468c-r0/package/usr/lib

and .debug contains

drwxr-xr-x 2 someuser someuser  4096 Nov 29 14:10 ./
drwxr-xr-x 3 someuser someuser  4096 Nov 29 14:10 ../

-rwxr-xr-x 2 someuser someuser 81500 Nov 29 14:10 libAnokiWave.so.1.0.1*

Which is incorrect, libAnokiWave.so and libAnokiWave.so.1 are not links.

I'm not really sure how to fix this. Would appreciate any help with it.

Check whether the situation is the same in .../image/usr/lib. If so, 
then the upstream is installing .so files incorrectly and you need to 
figure out what it does and how to fix it so that it symlinks .so 
instead of copying or hardlinking it.

Thanks for the reply. I changed do_install of my recipe

do_install () {
  install -d ${D}${libdir}/
  install -m 0755 ${S}/libAnokiWave.so.1.0.1 ${D}${libdir}
}

Now the error is gone and there are no warnings but if I check

/tmp/work/cortexa9hf-neon-xilinx-linux-gnueabi/anokiwavelib/1.0+gitAUTOINC+16df62468c-r0/package/usr/lib/

all I see is libAnokiWave.so.1.0.1

If I change my install task to

do_install () {
  install -d ${D}${libdir}/
  install -m 0755 ${S}/libAnokiWave.so.1.0.1 ${D}${libdir}
  ln -s ${D}${libdir}/libAnokiWave.so.1.0.1 ${D}${libdir}/libAnokiwave.so.1
  ln -s ${D}${libdir}/libAnokiWave.so.1 ${D}${libdir}/libAnokiwave.so
}

I get the following warnings

WARNING: anokiwavelib-1.0+gitAUTOINC+16df62468c-r0 do_package_qa: QA
Issue: Symlink /usr/lib/libAnokiwave.so.1 in anokiwavelib points to
TMPDIR [symlink-to-sysroot]
WARNING: anokiwavelib-1.0+gitAUTOINC+16df62468c-r0 do_package_qa: QA
Issue: Symlink /usr/lib/libAnokiwave.so in anokiwavelib-dev points to
TMPDIR [symlink-to-sysroot]

I'm not sure how to fix these issues. The links, libAnokiWave.so.1 and
libAnokiWave.so, must exist but right now they don't point to the
right location or doen't exist at all.

Would appreciate any help with this.

You need to call 'ln -sr', then you'll get relative symlinks. Better 
yet, add some build system support to the project (meson, cmake), then 
it'll take care of these things for you.

Thanks for the reply. It worked. I will definitely will look into
meson and cmake at a later time.
